ISQ Single Quadrupole GC-MS
The ThermoScientific ISQ is a single quadrupole, benchtop GC/MS instrument and is the 'work-horse' instrument for screening and characterising complex mixtures of volatile organic compounds. It is fitted with a programmable temperature vaporising (PTV) that can also be reconfigured to provide pseudo on-column injection and operates solely in electron ionisation (EI) mode. It is also equipped with a ThermoScientific AS1310 autosampler capable of holding up to 155 samples thereby maximising automated throughput. The facility owns and operates two of these instruments ensuring a high capacity for GC-MS analyses.
